Windows security basics: a practical checklist

Consistent habits can improve the security and reliability of a Windows PC.

Keep Windows and apps updated

Install security updates for Windows, browsers and commonly used applications. Enable automatic updates where appropriate and restart when required.

Review Windows Security

Open Windows Security and review protection areas. Check that antivirus and firewall settings are active. If you use another security product, follow its compatibility guidance.

Protect your accounts

• Use unique passwords and a reputable password manager.
• Enable multifactor authentication on important accounts.
• Use a standard account for everyday work where practical.
• Lock your PC when you step away.

Keep backups

Maintain a separate backup of important files and periodically check that you can restore them.

Be careful with downloads

Download software from its official publisher or a trusted app store. Avoid unexpected attachments, cracked software and installers promoted by alarming pop-ups.
